LOUIS BINSFELDT AND JOHN CHATEAU, OF DETROIT7 MICHIGAN.

COMBINED DOOR LOCK AND HINGE.

SPECIFICATION forming part of Letters Patent No. 404,590, dated June 4, 1889.

Application filed December 10, 1888. Serial No. 293,089. (No model.)

To @ZZ whom, it may 0071/067177.: Y

Be it known that we, LoUIs BINSEELDT, a citizen .of Holland, and'JoHN CHATEAU, a citizen of the United Statesyboth residing at Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in a Combined Door Lock and Hinge, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in a combined door lock and hinge; and the invention consists in the peculiar construction and in the combination and arrangement of the various parts, all as more fully hereinafter described and claimed.

In the drawings which accompany this specification, Figure l shows an elevation of the door mounted in position and provided with our improved device. Fig. 2 is a vertical central longitudinal section through the door and casing. Fig. 3 is a detached perspective view of the locking device for the top and bottom of the door. Fig. 4 is a crosssection through the door and casing on line X X in Fig. 2. Fig. 5 is an enlarged plan showing the center of the lock and its connections.

A is a doo;1 of the usual construction. B are the stiles. C is the bottom rail and D is the top rail of the door-casing, of usual construction, to which it is desired to apply our improved device. The door A is preferably provided upon each edge with a vertical groove E,which is preferably covered, to make a finished appearance, by the molding F.

G G are the vertical rods, of suitable size to loosely play in the groove E, connecting at their inner ends to suitable operating mechanism for simultaneously raising and lower- This rod-operatin g mechanismwe preferably construct as shown in detail in Fig. 5, wherein a is the casing, and bis the doorknob-spindle. c is a double cam secured thereon, and c and eare two levers pivotally secured at c4 to the casing and at their outer ends, respectively, by means of the links g4, to the rods G G in any suitable manner, and at their inner ends provided with suitable cfms cl to engage with the cams of the spindle. f is a spring interposed between the levers to normally hold the cams into engagement withthe cams on the spindle, all so arranged that y by turning the knob K in either direction the cam c actuates the levers e and e', thereby withdrawing the rods G and G toward the latch, and the faces g and g will hold the levers in their adj usted position if the knob is turned to the proper position. These rods are of suitable length to project slightly beyond the top and bottom of the door when in their extended position, as shown in Fig. 2. H H are suitable apertures in the top and bottom rails of the door-casing to receive the projecting ends of the vertical rods. l/Vearing-plates I I are preferably secured upon the door and the top and bottom rails of the casing at a point where the rod passes. The ends -of the vertical rods are provided with notches J J adapted to receive spring-latches K', preferably arranged at the top and bottom of the door-casing. These notches J J extend around the rods, except at one point, where the rod is smooth, the notches being in such relation to the spring-latch as to cause the latch to engage therein as soon as the door is opened, for the purposemore fully hereinafter described.

Suitable grooves L are provided in the top and bottom rails of the door-casing for a spring-latch, shown in detail in Fig. 3,wherein K is the latch, preferably a metal rod with suitably-sharpened ends, guided by suitable guides M, and actuated by a spring N, secured upon the latch and abutting against a stop O. The latch K is preferably arranged with the return-bend P at one end,for the purpose of simplifying the construction and of having' one latch secured with the rods on both sides of the door.

The threshold-strip and top rail are preferably beveled toward both sides at the points where the vertical rods enter, and Inay be provided with metal wearing-plates.

In practice, the parts being constructed and arranged as described, they are intended to operate as follows: The door being closed, to open it one of the door-knobs is turned,which withdraws the vertical bolts from engagement with the apertures at the top and bottom of the casing. The door is now free to swing, having for its hinge the vert-ical bolts upon the opposite edge. As soon as the door begins to swing open the spring-latch engages in the notches ol' the bolt and prevents the possibility of \\'itlnlra\\'ing the bolts at that side. The door being;l closed, the `vertical bolts impnge against the beveled edges of the threshold-strip and top rail until they reach the point opposite the apertures ll. Il', when the action oi? the spring` throws them into engagement therewith, and the door is thus held in its closed position.

Any suitable lock-such as shown at Q- y maybe used to lock the vertical bolts in their extended position. 1sVe preferably form the spring-bolts with the bend R, and deepen the groove E, as shown, for the purpose of preventing,` the twistingoli' the vertical bolts, and also to i'orm the shoulders I to aet as a stop ifor the bolts to prevent damage to the parts.

It will readily be understood that when the door is in its closed position, if both knobs are turned simultaneously, it may be taken out of the frame.

ltwill be seen that a door thus constructed will open in either direction and from either side, and that it may be taken from its posi tion without delay or trouble. lt is especially desirable for house use, where in summer no door is desirable, and in Winter the passage Way needs to be closed.

XVe do not desire to limit ourselves to any specific use; but

'W hat we claim as our invention 'ism l. A combined door lock and hinge, consisting ot vertical rods normally extended and adapted to enter suitable apertures in the threshold and top rail of a door-frame, combined with a latch arranged at right angles to said rods to engage the extended ends thereof, substantially as described.

2. A combined door lock and hinge, consisting of two pairs of vertical rods, a sprin adapted to normally expand them, suitable apertures in the threshold and top rail, and spring-catches adapted to engage with. the extended ends of the rods, substantially as described.

In a combined door lock and hinge, the combination of two pairs of vertical rods normally extended by a spring' beyond the top and bottom of the door, the notchessuch as .l J- in said extended portions, the s} n'ing-latehes K', adapted to engage in said notches, and suitable latch mechanism for operating the vertical rods, substantially as described.

i. In a door provided upon both edges with vertical grooves, caps or moldings, two pairs of spring actuated rods :in said grooves adapted to be used as a lock or hinge .t'or the door, eombin ed with spring-catches movable at right angles to said rods, substantially as described.

In testimony whereof: we affix our signatures, in presence of two witnesses, this lst day of November, 1888.
